BACKGROUND ART

Generally, a conventional multimedia contents broadcast is equipped with a radio communication network for broadcasting multimedia contents whose intellectual properties belong to individuals, and uses a system of a service provider who provides an individual multimedia contents broadcasting service based on the above radio communication network.

In more details, an individual multimedia contents broadcast might be performed by using a system belonging to a service provider which is equipped with a DHCP server which allocates a public IP to an individual user for a connection with a service provider's network based on a radio communication network after an individual broadcast radio frequency band is reported to a public organ, which controls and manages a radio communication, and receives an authentication from the same; an authentication server which manages the processes that an individual user connects to a multimedia contents DB server which is set by the service provider; a multimedia contents DB server of the service provider which stores an original version multimedia contents or edited multimedia contents whose intellectual properties belong to individual users; and a playback tool storing server which provides playback tools so that a certain user can playback a corresponding multimedia contents stored in the multimedia contents DB server of the service provider.

However, it is disadvantageous that an individual multimedia contents broadcast using a service provider's system should use a radio frequency band authenticated by a public organ which controls and manages a radio communication, and an individual user should pay a service charge for the use of a radio communication network and should further pay a service charge for the use of a public IP used for a connection with the service provider's system. In addition, the individual users should all request services on the use of a service provider's system so as to use a multimedia contents DB server of the service provider. The individual users are needed to have individual user's authentications from the service providers all the time whenever connecting to the service provider's system. The individual users should use the above system even though they feel a lot of inconvenience in the use of the above systems. In worse case, it is needed to assign the intellectual properties of the multimedia contents belonging to the individual users to the service provider.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a schematic view of an individual multimedia contents broadcast system according to a preferred embodiment of the present invention. As shown in FIG. 1, an individual multimedia contents broadcast system according to the present invention comprises a receiving terminal 300, a radio network, and an individual multimedia contents broadcasting equipment 100 a.

The receiving terminal 300 is connected to an individual multimedia contents broadcasting equipment 100 a as it requests a connection to an individual multimedia contents broadcasting equipment 100 a through a radio network formed by means of an individual multimedia contents broadcasting equipment 100 a depending on a user's operation and receives a private IP.

The receiving terminal 300 is capable of receiving and playing back the broadcast contents from the individual multimedia contents broadcasting equipment 100 a.

The receiving terminal 300 might be a mobile communication terminal having an input unit such as an operation unit 104 a, an output unit such as a speaker 104 d and a LCD 104 e, and a radio communication unit 102 for a data receiving and transmission through the radio network or might be a portable individual information communication instrument such as a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or the like. Here, the radio network according to the present invention is constructed to perform a radio data communication based on the IEEE 802.11 protocol. So, there is provided a radio communication unit 102 which supports a data communication based on the IEEE 802.11 protocol. The radio network according to the present invention might be configured to use various universal radio data communication protocols except for the IEEE 802.11 if necessary. The construction and functions of the receiving terminal 300 will be described later with reference to FIG. 3.

The individual multimedia contents broadcasting equipment 100 a creates and stores broadcast multimedia contents depending on a broadcaster's operation and allocates a private IP depending on a connection request of the receiving terminal 300 and forms a radio network and transmits a broadcast multimedia content selected by means of a broadcaster's operation. The individual multimedia contents broadcasting equipment 100 a might be equipped with an input unit such as an operation unit 104 a, a microphone 104 b, a camera 104 c or something, an output unit such as a speaker 104 d, a LCD 104 e or something, a mobile communication terminal having a radio communication unit 102 for a data receiving and transmission through a radio network, and an individual information communication instrument such as a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or something. The functions and constructions of the individual multimedia contents broadcast equipment 100 a will be described with reference to FIGS. 2A and 2B.

Here, the radio network created and maintained by means of the individual multimedia contents broadcasting equipment 100 a is designed to use an ISM (Industrial, Science and Medical) radio frequency band or a U-NII 5 GHz radio frequency band. The ISM radio frequency band is a frequency band allocated by the FCC for the use in industry, a science and a medical field. 902-928 MHz, 2.4 G-2.4835 GHz and 5.725 GHz-5.835 GHz frequency bands are set for the ISM bands. These frequency bands are not needed to have ant permission for a frequency allocation. The output of the equipment which uses the above frequency bands is 17 dBm/50 mW. The U-NII 5 GHz radio frequency band is a frequency band used in the IEEE 802.11a and HIPERLAN/2 which also does not need any permission for a frequency allocation.

In the present invention, 802.11a, 802.11b or 802.11g might be used or properly combined for a LAN radio communication. The 802.11a, 802.11b and 802.11g are the protocols for a radio LAN developed by the IEEE work group. The above three protocols use CSMA/CA which is an Ethernet protocol. The 802.11b provides a rate of 11 Mbps per second, whereas the latest 802.11g provides a relatively shorter distance communication at a rate of 54 Mbps in maximum. Since the 802.11g works in a 2.4 GHz band like 802.11b, there is compatibility between the above two protocols. The modulation method used in 802.11 is traditionally PSK, but the modulation applied in 802.11b provides a faster data transmission rate, and uses CCK which is not interfered with multiplexed transmission passages. The 802.11a is generally used in a radio ATM system, namely in an access hub. The 802.11a is applied in a radio frequency bandwidth of 5 GHz-6 GHz. The 802.11a uses a modulation method which is called an OFDM for a data transmission rate up to 54 Mbps in maximum.

In case of 5 GHz band, since it is a relatively higher frequency, it is not proper that other small compact sized radio devices might compete with one another for frequencies. The IEEE 802.11a has much less interferences by means of other devices as compared to the IEEE 802.11b and advantageously supports a faster transmission rate of 54 Mbps. It is preferred that the radio network according to the present invention is configured in an independent network for a personal broadcasting service provided using a private IP through a DHCP function of the individual multimedia contents broadcasting equipment 100 a.

It is disadvantageous that the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g might be used only for the LAN radio communication. So as to overcome the above disadvantages, the individual multimedia contents broadcasting equipment according to the present invention might be further equipped with an individual multimedia contents relay broadcasting equipment 100 b. The individual multimedia contents relay broadcasting equipment 100 b is configured in the same manner as the individual multimedia contents broadcasting equipment 100 a. A private IP is allocated from the individual multimedia contents broadcasting equipment 100 a in a radio communication radius of the individual multimedia contents broadcasting equipment 100 a, and the individual broadcast received depending on a request of the receiving terminal 300 c in a relay radio network range, which requests a received individual broadcast viewing, is relayed. Namely, the individual multimedia contents broadcasting system according to the present invention can overcome the problems of the radio data communication radius by using the individual multimedia contents relay broadcasting equipment 100 b, so it is possible to watch an individual broadcast from a relatively farther distance.

FIG. 2A is a block diagram of a physical internal construction of an individual multimedia contents broadcasting equipment in an individual multimedia contents broadcasting which uses an ISM radio frequency band or a U-NII 5 GHz radio frequency band.

As shown in FIG. 2A, the individual multimedia contents broadcasting equipment 100 a according to the present invention comprises an input and output unit 104, an individual broadcast process unit 103, a radio communication unit 102, an antenna 101, and a power supply unit 105.

The input and output unit 104 includes an input part and an output part.

The input part is formed of at least one among an operation unit 104 a for receiving a control signal based on a broadcaster's operation, a microphone 104 b for receiving a sound data, and a camera 104 c for receiving a video data. The output part is formed of at least one between a speaker 104 d for outputting a sound data, a LCD 104 e for outputting a video data and something. Here, the operation unit 104 a represents an input device such as a keypad, a keyboard, a mouse, a touch screen or something. The microphone 104 b and the camera 104 c might be formed of a microphone 104 b and a camera 104 c provided in the individual multimedia contents broadcasting equipment 100 a or might be formed of an external microphone 104 b and a camera 104 c connected through an interface part such as a USB port. The input and output unit 104 is configured by using a known art. So, the detailed descriptions of the same will be omitted.

The individual broadcast process unit 103 creates and stores broadcast contents using a data inputted through an input unit and provides a receiving terminal, which requests a connection, with a private IP for thereby connecting through a radio network and transmits broadcast contents to the receiving terminal connected. More preferably, the individual broadcast process unit 103 according to the present invention includes a broadcast module 103 c, a storing device 103 b and a controller 103 a.

The broadcast module 103 c creates and stores broadcast contents using a data inputted through an input unit depending on a broadcaster's operation and provides a private IP to the receiving terminal 300 which requests a connection for thereby connecting through a radio network and transmits an individual multimedia content to the connected receiving terminal 300 based on a broadcaster's selection. At this time, the individual broadcasting multimedia contents broadcasted through the receiving terminal 300 according to the present invention might be a text data, a symbol data, a music data inputted through the microphone 104 b, a sound data, an audio data, a video data inputted through the camera 104 c, an image data, a photo data or a combination of the same.

The individual broadcasting multimedia contents according to the present invention might be an individual broadcasting multimedia content created in real time from the broadcasting module 103 c depending on a broadcaster's operation, an individual broadcasting multimedia content stored in the storing device 103 b, an individual broadcasting multimedia content created in real time, an individual broadcasting multimedia content stored in the storing device 103 b or a combination of the same and might be transmitted. When a broadcaster selects a real time broadcast by operating the individual multimedia contents broadcasting equipment 100 a, the individual multimedia contents broadcasting equipment 100 a according to the present invention creates an individual broadcasting multimedia content using a sound data, an audio data, a text data and a video data inputted in real time from the input unit, and transmits in real time to the receiving terminal 300. When the broadcaster selects a recording broadcast, the individual broadcasting multimedia content previously created and stored in the storing device 103 b is transmitted to the receiving terminal 300. When the broadcaster selects a combined content (for example, when a specific content previously created and stored in the storing device 103 b is selected as a background image, and when it is combined with a motion image inputted in real time on the background image and it is broadcasted), the contents combined with the individual broadcasting multimedia contents created in real time and the individual broadcasting multimedia contents stored in the storing device 103 b are transmitted to the receiving terminal 300.

The storing device 103 b includes various programs used for driving the individual multimedia contents broadcasting equipment 100 b and stores an individual broadcasting multimedia content created from the broadcasting module 103 c depending on a broadcaster's selection. The storing device 103 b might be formed of various universal storing devices such as a hard disk drive, a ram disk drive or something.

The controller 103 a controls a broadcast module 103 c, a storing device 103 b, an input and output unit 104 and a radio communication unit 102 depending on a control signal inputted through the operation unit 104 a, and creates an individual broadcasting multimedia content and performs an individual multimedia contents broadcasting.

The radio communication unit 102 forms a radio network and performs a data communication with the receiving terminal 300 connected through a radio network and is configured to substantially support the IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n which are selected depending on the needs in the individual multimedia contents broadcasting system according to the present invention.

As shown in FIG. 2B, the broadcast module 103 c according to the present invention comprises an input and output module 202, an individual broadcast process module 200, and a radio communication module 201. The input and output module 202 is a device drive of an input and output unit and controls a data input through the input unit and a data output through the output unit, and the radio communication module 201 is a device drive of the radio communication unit 102 and controls the radio communication unit 102 and broadcasts the individual broadcasting multimedia contents on the receiving terminal 300 depending on the broadcaster's operation.

The individual broadcast process module 200 is a key module for performing an individual multimedia contents broadcasting according to the present invention and creates and stores a multimedia content using the data inputted from the input unit and allocates a private IP through a DHCP (Dynamic Host Configuration Protocol) to the receiving terminal which requested a connection and sets a connection or retrieves the provided private IP and disconnects the connection and transmits an individual broadcasting multimedia content to the connected receiving terminal 300 based on the broadcaster's selection. So as to perform the above operations, the individual broadcast process module 200 comprises a DHCP module 200 a, a private IP management module 200 b, an authentication module 200 c, a playback tool management module 200 d, a connection terminal management module 200 e, and a content creation module 200 f.

The content creation module 200 f creates a text data and a symbol data inputted through the individual broadcasting multimedia content operation unit 104 a using a data inputted through the input unit, a music data, a sound data and an audio data inputted through the microphone 104 b, and a video data, an image data and a photo data inputted through the camera 104 c and combines the same. So as to perform the above operations, the content creation module 200 f according to the present invention is configured to support a text/symbol input function, a music/sound encoding function, a photo/motion picture encoding function or something. It further supports a combining and encoding function for a mixed content creation. Here, the encoding codes might be selected from mp3, wma, jpg, asp, mpeg, xvid or something. An exclusive codec might be used.

The DHCP module 200 a allocates a private IP through a DHCP function to the receiving terminal 300 connected, and sets a connection or retrieves the allocated private IP and disconnects the connection. Namely, the DHCP module 200 a according to the present invention performs a DHCP server function and sets a private IP in the receiving terminal 300, which requested a connection in an individual broadcasting independent radio network, by using a private IP information stored in the private IP management module, so the individual broadcasting independent radio network might be configured, and the individual broadcasting might be watched.

The private IP management module 200 b stores and manages a private IP information to be allocated to the receiving terminal 300, and a private IP information allocated to the current receiving terminal 300. The private IP information created and stored by the private IP management module 200 b is referred by means of the DHCP module 200 a, so a private IP to be allocated to the receiving terminal 300 is determined. When the private IP is allocated to the receiving terminal 300 or is retrieved, and the connection is disconnected, the above operation is updated in real time.

The playback tool management module 200 d judges whether the content playback tool is installed or not in the connected receiving terminal 300. When it is not installed, the multimedia content playback tool stored in the storing device 103 b is transmitted to the receiving terminal 300 and is automatically installed, so the multimedia contents can be played back. At this time, the multimedia content playback tool installed in the receiving terminal 300 is configured to decode the encoded multimedia data depending on the adapted encoding codec or a codec previously installed in the receiving terminal 300 might be used or a certain codec might be previously installed in the multimedia content playback tool.

When the broadcaster selects an authentication function, the authentication module 200 c performs an authentication using terminal information, so that only the authenticated receiving terminal 300 can view an individual broadcast. So as to perform the above operations, the authentication module receives registration information from a new terminal (or user) who wants to view the individual broadcast, and creates an authentication information and stores in the storing device 103 b, for thereby finishing a new registration. The authentication information stored in the storing device 103 b is compared with the authentication information (terminal information or user information) received from the connected receiving terminal, so a needed authentication is performed. As a result, when the authentication is succeeded, the content receipt of the receiving terminal 300 is permitted, and when the authentication is failed, the private IP provided to the receiving terminal 300 is retrieved, and the connection is finished.

The connection terminal management module 200 e monitors in real time connection information including at least one among the number of connected receiving terminals, a connection state, a radio communication sensitivity or something and displays the current connection information on the LCD 104 e temporarily or periodically depending on the previously set information and provides to the broadcaster in real time. The real time connection information monitored by means of the connection terminal management module 200 e is stored in the storing device 103 b in a DB form. The connection terminal management module 200 e extracts and provides connection information stored in the database when the broadcaster requests a connection data such as connection information of a certain time period or a specific time section or provides the broadcaster with a statistic data.

The individual multimedia contents broadcasting equipment 100 b according to the present invention receives an allocation of the private IP from other individual multimedia contents broadcasting equipments 100 a for thereby receiving the contents broadcasted by means of another individual multimedia contents broadcasting equipment 100 a. So, the individual multimedia contents broadcasting equipment 100 b according to the present invention performs a relay broadcast in a relay region where requests a receipt of the multimedia contents received from another individual multimedia contents broadcasting equipment 100 a. The individual multimedia contents broadcasting equipment 100 b having a relay function is formed in the same construction as the individual multimedia contents broadcasting equipment 100 a which performs the above broadcasting functions, provided that there are differences only in the contents received from the individual multimedia contents broadcasting equipment 100 a. So, the construction and operations of the same will be omitted. The above relay function is provided for overcoming the limits in the LAN radio communication radius. When the relay function is used, an expansion of the independent radio network for an individual broadcast might be possible. The relay function will be described later with reference to FIGS. 5 and 6.

The individual multimedia contents broadcasting equipment 100 a according to the present invention might be configured in fixed broadcast equipment or portable broadcast equipment. In case of the fixed type, an individual information communication instrument such as a desk top system except for a portable or mobile communication instrument might be used. In case of the portable type, a portable individual information communication instrument such as a mobile communication terminal, a PDA, a palm top computer, a UMPC, a navigation device, a portable game unit or something might be used. The individual multimedia contents broadcasting equipment 100 b having a relay function might be a mobile system while maintaining a radio communication radius which is a relatively shorter distance as compared to the fixed type.

FIGS. 3 is a block diagram of an inner construction of a receiving terminal which is capable of receiving individual multimedia contents broadcasting which uses an ISM radio frequency band or a U-NII 5GHz radio frequency band.

As shown in FIG. 3, the receiving terminal 300 according to the present invention comprises an antenna 10 a, a radio communication unit 102, a processor 103 a, a storing device 103 b, an input and output unit 104, and a power supply unit 105. The above elements are key parts in the individual information communication instrument and operate in the same manner as the elements of the individual multimedia contents broadcasting equipment 100 a. So, the detailed descriptions of the same will be omitted. The receiving terminal 300 according to the present invention is equipped with a multimedia contents playback tool (not shown) which is used for playing back the contents from the individual multimedia contents broadcasting equipment 100 a. When the logically operable broadcast module 103 c is integrally provided in the system, not being independent from the contents playback tool, and is installed in the receiving terminal 300, the receiving terminal 300 receives broadcast contents from the other receiving terminal (individual multimedia contents broadcasting equipment 100 a) and plays back the same. When the user wants, the user can perform own individual broadcast using the broadcast module 103 c. When the broadcast module 103 c and the contents playback tools are separately installed, it is needed to install both the broadcast module 103 c and the contents playback tool for each corresponding function.

FIG. 4 is a flow chart of an individual broadcast procedure of the individual multimedia contents broadcasting equipment in the individual multimedia contents broadcasting which uses an ISM radio frequency band and a U-NII 5 GHz radio frequency band according to the present invention. The individual broadcast manufacturing method according to the present invention will be described with reference to FIG. 4.

An individual broadcast driving instruction inputted through the operation unit 104 a depending on a broadcaster's operation is interpreted by means of a key input module 202 a, and is transmitted to the controller 103 a. The controller 103 a judges whether the multimedia contents stored in the storing device 103 b are broadcasted or the multimedia contents inputted through the input and output unit 104 are broadcasted in real time in a step S400.

In case that the individual broadcast driving instruction corresponds to a recording broadcast in which the multimedia contents stored in the storing device 103 b are broadcasted, the controller 103 a transmits the multimedia contents stored in the storing device 103 b to the radio communication instrument 102, and a corresponding broadcast beings in a step S402.

When the broadcaster selects a real time broadcast, the text data and symbol data inputted trough the operation unit 104 a are interpreted by means of the key input module 202 a, and the music data, audio data and sound data inputted through the microphone 104 a are interpreted by means of the audio input module 202 b, and the image data, image data, and photo data inputted through the camera 104 c are interpreted by means of the video input module 202 c. The above data are sequentially transferred to the controller 103 a in a step S401. The controller 103 a creates multimedia contents in real time in a sequence of the input, and stores into the storing device 103 b, and transmits the multimedia contents created in real time through the radio communication unit 102, and the broadcast begins.

In the steps S402 and S403, the multimedia contents, which are individually broadcasted, are outputted to the speaker 104 d by the process of the controller 103 a, and the music data, audio data and sound data are outputted to the speaker 104 d through the audio output module 202 d. The video data, image data, and photo data are outputted to the LCD 104 e through the video output module 202 e. The broadcaster performs a broadcast while checking the contents of the multimedia contents which are being broadcasted through the output unit of the individual multimedia contents broadcasting equipment 100 a.

In the step S401, when the multimedia contents stored in the storing device 103 b with a periodically repeated judgment process after the individual broadcast has begun are broadcasted, the multimedia contents inputted through the input and output device 104 are combined with the multimedia contents of the storing device 103 b depending on the process of the processor 103 a as a result of the judgment of the step S401 and are broadcasted.

Next, the controller 103 a judges a connection request of the receiving terminal 300. When there is a request, a private IP allocable to the receiving terminal 300 which requested a connection with reference to the current private IP information managed by means of the private IP management module 200 b through the DHCP module 200 a is selected and automatically allocated to the receiving terminal for thereby setting a connection in steps S404 and S405.

When an authentication function is not activated after a connection is set, the authentication module 200 c receives authentication information from the connected receiving terminal 300 and compares with the authentication information stored in the storing device 103 b for thereby judging whether the connected receiving terminal is the receiving terminal 300 registered in the connection terminal management module 200 e in steps S406 and S407.

As a result of the judgment of the registration, when the connected receiving terminal is not the authenticated receiving terminal 300, the allocated private IP is retrieved, and the connection is automatically disconnected, and the broadcast receipt is prohibited in a step S408, and in case of the authenticated receiving terminal, the step S409 is performed.

Next, the controller 103 a judges whether there is a playback tool in the authenticated receiving terminal 300 for playing back the broadcast contents with the helps of the playback module 200 d in a step S409, and when a playback tool is not installed, the playback tool stored in the storing device 103 b is transmitted to the receiving terminal 300 using the playback tool module 200 d and is installed in a step S410. When an individual content can be played back in the receiving terminal 300, the controller 103 a transmits a currently broadcasting content selected by the broadcaster to the receiving terminal 300, and the receiving terminal 300 receives the broadcast content and plays back the same. At this time, the connection terminal management module 200 e of the individual multimedia contents broadcasting equipment 100 periodically transmits a connection state of the receiving terminal 300 to the video output module 202 e, and the video output module 202 e indicates the connection state of the receiving terminal 300 on the LCD 104 e and periodically manages the same.

When the individual broadcast is continuously performed, the routine is repeated from the step S401 to the step S412. When it is judged that the individual broadcast is finished, the individual broadcast operation is stopped in a step S412.
